Hello, is the any way we can get AE expression to work in Lottie? I am curious if there’s any development or future plans on this. ---

hey, not sure if it’s your question, but you have already a box to check in bodymoving’s options to export ae expressions ![Capture d’écran 2022-02-14 à 19.26.29](https://canada1.discourse-cdn.com/flex030/uploads/lottiefiles/original/2X/6/697152f700d6c25c5787da15439dc707db05a71a.png) ---

Also you can right click an expression and covert it to keyframes ---

Basically I linked a colour property in Comp A \> Layer A to another colour property in Comp B \> Layer B using a simple expression, so that every time I change the colour of Layer B, Layer A will change its colour too. It works fine in AE. But when I export it to JSON using Bodymovin, and eventually use it for my app (by the way I am using Flutter to build my app), I need to change the colour dynamically too. Sadly the expression between layer A and B isn’t working anymore. I am wondering if there’s a work around for this. Any idea? ---

Not exactly what I want to do. I am wondering if there’s any workaround so that we can use AE’s expression in Lottie without converting it to keyframes. ---

@surya would this video help? It pretty much covers what you’re talking about maybe it can be hacked around for Flutter [![](https://canada1.discourse-cdn.com/flex030/uploads/lottiefiles/original/2X/3/36bb1b2b72d69c6a2b72964aaae6f88963f86a48.jpeg "Dynamically Change Lottie Animations with Expression Controls") ](https://www.youtube.com/watch?v=XX8jwNNV0U0) ---

Appreciate your help. but unfortunately it doesn’t work for my purpose because I need it for mobile app. Seems like expressions don’t work only for iOS and Android. Curious if there will be development on this in the future.
